Through modern advances in science and technology, those ancient barriers to communication, time, and space, have been banished by new and startling tools. We have come a long way since the days of the clay tablet, the ballad singers, the parchment scroll; yes, since Gutenberg and the invention of movable type. Recently, we have been given other tools which combine visual and oral technique to produce a more dramatic, forceful, and concrete presentation of information and ideas. What was once the magic lantern has been replaced by the slide or film-strip projector. The cumbersome stereopticon has become a sleek optical viewer that provides third-dimensional depth for photographic transparencies. The motion picture film and the radio transmit information to millions of homes and classrooms, and the advances made in television have brought an even more vivid and concrete sharing of people's ideas and ideals, of the events of the world, hour by hour. Thus, the form, color, and sound of what takes place anywhere may be simultaneously observed everywhere. The latest spectacular development, called ultrafax, combines radio, television, and photography to send a million words a minute between distant points or to transmit a picture, map, or document in seconds. When fully developed ultrafax may perform revolutionary tasks in the field of communications.
